@tsarstepan,
She is. Incidentally, that's the age at which both my sister A. and I read the diary of Anne Frank -- also not a book for fans of sugar-coated literature. We did get upset about numerous things, obviously. But the book was a page-turner then, and we're still grateful today that we read it early in our lives. So,
Iron-Jawed Angels may be appropriate for Sozlet, or it may be not. Hence the suggestion to pre-screen.
